SQL Server Reporting Services connection issues

I can connect to sql server reporting services both in the browser and through studio manager, but with problems.

In the browser, there's no "site sections" at the top or anything in the tab area (content, etc).

In Studio Manager, when I expand the "Home" node, I get the error "Failed to retrieve data for this report.....The permissions gr开发者_如何学Goanted to user '[computer name]\anonymous user]' are insufficient for performing this operation. (rsAccessDenied)...."

Os: Windows XP Professional SQL Server 2005

Thank you.
